Configuring sound outputs of Windows 7. Installing the Realtek driver

Good day.

This article, based on personal experience, is a kind of collection of reasons due to which sound may disappear on a computer. Most of the reasons, by the way, can be easily eliminated by yourself! To begin with, you should distinguish that the sound can be lost for software and hardware reasons. For example, you can check the performance of the speakers on another computer or audio / video equipment. If they are working and there is sound, then most likely questions are about the software part of the computer (but more on this).

And so, let's get started ...

6 reasons why there is no sound

1. Non-working speakers (cords often bend and break)

This is the first thing to do when setting up sound and speakers on your computer! And then, sometimes, do you know, there are such incidents: you come to help a person to solve the issue with the sound, and he turns out to have forgotten about the wires ...

Plus, you may have connected them to the wrong input. The fact is that the sound card of a computer has several outputs: for a microphone, for speakers (headphones). Typically, for the microphone, the output is covered in pink, for the speakers - in green. Pay attention to this! Also, here is a small article about, there this issue was analyzed in more detail.

Rice. 1. Cord for connecting speakers.

Sometimes it happens that the inputs are very worn out, and they just need to be slightly corrected: remove and reinsert. You can also clean your computer from dust, at the same time.
Also pay attention to whether the columns themselves are included. On the front of many devices, you can see a small LED that signals that the speakers are connected to the computer.

Rice. 2. These speakers are on because the green LED on the device is on.

By the way, if you turn the volume up to maximum in the speakers, you can hear a characteristic “hiss”. Pay attention to all this. Despite the elementary nature, in most cases there are problems with just this ...

2. The sound is turned off in the settings

The second thing to do is to check if everything is in order with the computer settings, perhaps in Windows the sound is programmatically reduced to a minimum or disabled in the control panel for sound devices. Perhaps, if it is simply reduced to a minimum, there is sound - it plays very weakly and is simply not audible.

Let's show the setting using the example of Windows 10 (in Windows 7, 8 everything will be the same).

1) Open control Panel, then go to the section " equipment and sounds«.

3) You should display audio devices (including speakers, headphones) connected to the computer in the "sound" tab. Select the required dynamics and click on their properties (see Fig. 4).

4) In the first tab that opens in front of you ("general"), you need to look carefully at two things:

• - was the device detected? If not, you need drivers for it. If they are not there, use one of the utilities for, the utility will also recommend where to download the required driver;
• - look at the bottom of the window to see if the device is turned on. If not, be sure to turn it on.

5) Without closing the window, go to the "levels" tab. Look at the volume level, it should be over 80-90%. At least until you get a sound, and then adjust it (see Fig. 6).

Rice. 6. Volume levels

6) In the "additional" tab there is a special button for checking the sound - when you press it, you should play a short melody (5-6 sec.). If you do not hear it, go to the next step, saving the settings.

Rice. 7. Sound check

7) You can, by the way, once again go to " control panel / hardware and sounds"And open" volume settings", As shown in fig. eight.

Here we are interested in whether the sound is reduced to a minimum. By the way, in this tab you can turn down the sound, even of a certain type, for example, all that is heard in the Firefox browser.

8) And the last.

In the lower right corner (next to the clock) there are also volume settings. Check if there is a normal volume level and if the speaker is not muted, as in the picture below. If all is well, you can skip to step 3.

Rice. 10. Adjusting the volume on the computer.

Important! In addition to the Windows settings, be sure to pay attention to the volume of the speakers themselves. Perhaps the regulator is at a minimum!

3. No driver for sound card

Most often, the computer has problems with the drivers for video and sound cards ... That is why, the third step in restoring sound is to check the drivers. You may have already identified this problem in the previous step ...

To determine if they are okay, go to device Manager... To do this, open control Panel, then open the tab “ Hardware and Sound"And then run device Manager... This is the fastest way (see Figure 11).

In the device manager, we are interested in the " Sound, game and video devices". If you have a sound card and it is connected: it should be displayed here.

1) If the device is displayed and a yellow exclamation mark (or red) is lit in front of it, then the driver is not working correctly, or is not installed at all. In this case, you need to download the driver version you need. By the way, I like to use the program - it will show not only the device model of your card, but also tell you where to download the necessary drivers for it.

A great way to update and check your drivers is to use the auto-update and driver lookup utilities for any hardware on your PC:. Highly recommend!

2) If there is a sound card, but Windows does not see it ... Anything can be here. It is possible that the device is not working properly, or you connected it poorly. I recommend first cleaning the computer from dust, blowing out the slot if you do not have a built-in sound card. In general, in this case, the problem is most likely with the hardware of the computer (or the fact that the device is turned off in BIOS, see about Bose just below in the article).

Rice. 12. Device Manager

It also makes sense to update your drivers or install drivers of a different version: older or newer. It often happens that developers are not able to foresee all possible computer configurations and it is possible that some drivers in your system conflict with each other.

4. No codecs on audio / video

If, when you turn on the computer, you have sound (you can hear, for example, the Windows greeting), and when you turn on any video (AVI, MP4, Divx, WMV, etc.) - the problem is either in the video player, or in the codecs, or in the file itself (it may be corrupted, try opening another video file).

1) If there is a problem with the video player, I recommend that you install another one and try it. For example, a turntable - gives excellent results. It already has built-in and optimized codecs for it, so it can open most video files.

2) If the problem is with the codecs, I would advise you to do two things. The first is to completely remove your old codecs from the system.

And second, install the full set of codecs - K-Lite Codec Pack. Firstly, this package has an excellent and fast Media Player, secondly, all the most popular codecs will be installed, which open all the most popular video and audio formats.

An article about K-Lite Codec Pack codecs and their correct installation:

By the way, it is important not only to install them, but to install them correctly, i.e. full set. To do this, download the full set and during installation select the "Lots of Stuff" mode (for more details on this in the article about codecs - the link is just above).

Rice. 13. Configuring codecs

5. Incorrectly configured BIOS

If you have a built-in sound card, check the BIOS settings. If the sound device is turned off in the settings, then you are unlikely to be able to make it work in Windows. To be honest, this problem is usually rare. by default in the BIOS settings - the sound card is enabled.

To access these settings, press the F2 or Del button (depending on the PC) while turning on the computer. If you cannot get in, try looking at the computer boot screen as soon as you turn it on, more closely. Usually a button for entering BIOS is always written on it.

For example, the ACER computer is turned on - the DEL button is written at the bottom - to enter the BIOS (see Fig. 14).

Rice. 14. Bios login button

In BIOS, you need to search for a line containing the word " Integrated«.

Rice. 15. Integrated Peripherals

In the list, you need to find your audio device and see if it is turned on. In Figure 16 (below) it is enabled, if you have “Disabled” opposite you - change it to “Enabled” or “Auto“.

Rice. 16. Enabling AC97 Audio

After that, you can exit BIOS by saving the settings.

6. Viruses and adware

Where are we without viruses ... Moreover, there are so many of them that it is not known what they can generally present.

First, pay attention to the overall performance of your computer. If there are frequent, antivirus triggers, "brakes" out of the blue. You may have actually contracted a virus, and more than one.

The best option would be to check your computer for viruses with some modern antivirus with updated databases. In one of the articles earlier, I cited the best ones at the beginning of 2016:

By the way, the antivirus shows good results, it is not even necessary to install it. Just download and check.

Secondly, I recommend checking your computer using a USB flash drive (the so-called Live CD). Whoever has never come across, I will say: you seem to boot from a CD (flash drive) a ready-made operating system, which has an antivirus. By the way, it is possible that you will have a sound in it. If so, then most likely you have problems with Windows and you may have to ...

7. Recovering sound if all else fails

Here are some tips to help you.

1) If you used to have sound, but now you don't, you may have installed some programs or drivers that caused a hardware conflict. It makes sense to try this option.

2) If there is another sound card or other speakers, try connecting them to the computer and reinstalling the drivers on them (while removing the drivers from the system for the old devices that you disabled).

3) If all the previous points did not help, you can take a chance and. Next, immediately install the sound drivers and if suddenly a sound appears - carefully look after it after each installed program. Most likely, you will immediately notice the culprit: a driver or a program that previously conflicted ...

4) Alternatively, connect headphones instead of speakers (instead of headphones - speakers). Perhaps it is worth contacting a specialist ...

The multimedia capabilities of a PC are used not only by lovers of computer games and connoisseurs of high-quality cinema, but even those users who, for example, keep accounting records, print documents or retouch photographs. Many people are not averse to distraction and listen to good quality music or watch videos on the Internet during their lunch break. One way or another, playing multimedia content first of all requires serviceability and proper adjustment of sound equipment.

Usually, even during installation, the system selects the most suitable drivers for each device, including for a sound card, but there are times when audio playback becomes impossible. The problem in this case can be either software or hardware. Hardware problems are related to the breakdown of speakers or sound cards and can only be solved by repairing or replacing damaged components, software failures are much easier to eliminate.

In order to find out what type of problem you are dealing with in each specific case, it would be nice to have an initial idea of ​​how the sound is actually formed in your computer or laptop:

1. Initially, information recorded on a digital medium, such as a USB flash drive or DVD, goes straight to the computer's motherboard.
2. Further, with the help of a built-in chip or by means of a separate card, the received information is processed and decoded into an analog format, which is fed to speakers or headphones.

Method 1: mechanical

For many users who are accustomed to working on a laptop, but "forced" to master orientation on a stationary computer in the office or at home, there is some confusion associated with the abundance of connected wired devices such as a keyboard, mouse, webcam and speakers. Therefore, if the sound disappears (especially suddenly), first of all, you need to make sure that the connection has not been broken, and the wires do not have strong bends. Next, you need to make sure that the speakers are connected to the appropriate connector ("Output") located on the motherboard or audio board. If the sound card is multi-channel and you connect a system of six speakers with a subwoofer, then you should carefully (according to the instructions or the colors of the connectors) connect all the plugs in pairs. After all the switching is done, you need to go to the "Control Panel" through the "Start" quick access menu and enable the "Surround Sound" function in the settings.

What else is worth knowing about?

• Usually, the connector into which the speakers are connected is green and the inscription Out is directly above the jack itself.
• If you are using a dedicated HDMI cable, remember that not all devices support this type of connection. In the "Control Panel" of Windows, you can configure the synchronization of the "hardware" with the cable by clicking on "Default setting".
• In the case of using USB devices that reproduce sound, you can try to plug them into another slot, after which the computer must be restarted.

A knob called Volume is responsible for the volume of the speakers. If you connected the speakers correctly, turned the volume control to the maximum, and the sound did not appear on the computer, then you can proceed to further search for the cause of the problem.

Method 2: sound card drivers

Method 3: check parameters

Method 4: neutralize Win audio crashes

Method 5: fix incorrectly configured BIOS

Method 6: installing codecs

If sound is present during the boot of the Windows operating system, but it disappears immediately during games or watching multimedia content, then the problem most likely lies in hopelessly outdated codecs, or in their complete absence.

Method 7: look in the "taskbar"

If the sound on the device has disappeared completely, or has a very low volume level, then it can be adjusted by clicking on the speaker image near the clock icon in the "Taskbar". After pressing you will have access to the adjustment menu called "Mixer". If the speaker image is crossed out in red, it means that it needs to be removed manually. If the volume slider is at the bottom, then it must be raised to the maximum. Here, in the "Mixer" you can also adjust the frequency and bit depth of the audio, as well as all sorts of "chips" like surround sound.

Method 8: using additional software

When you cannot adjust the sound on your computer yourself, you can use special programs that can diagnose the problems that have arisen and, accordingly, eliminate the cause of the failure. Some manufacturers of audio components accompany their devices with similar utilities, or they can be downloaded from the developer's official website.

In contact with

It is difficult to imagine a more ridiculous situation than watching the next issue of Comedy club on a PC without sound. At the same time, this kind of computer malfunction is far from uncommon in user practice. A great example of this is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, the "unauthorized boycott" announced by your PC is definitely an unpleasant surprise for many novice users. Especially when you consider that the problem with sound is quite multifaceted in resolution. However, you, dear reader, are in luck again! Because in just a few minutes you will be able to "untie the tongue" of virtually any Windows operating system. Well, let's not waste precious time - let's turn to the experience of professionals.

Diagnostics of the computer "muteness"

The answer to the question of how to restore sound on a computer needs to be looked for in two ways. The fact is that most often the system "loses its voice" due to software failures. However, the sound may disappear as a result of hardware failure. For example, an integrated audio chip. To understand what exactly is the cause of "silence", you need to resort to a step-by-step plan of action. Only after a thorough practical analysis will you be firmly convinced of whether your audio malfunction is hardware or software. However, let's not talk about the bad - everything should be decided without the intervention of a specialist.

Step number 1. Elementary check

Tell me how to turn on the sound on the computer if the speakers are inoperative or simply not connected? Of course, no way! Exceptionally simple steps can help you avoid mistakes and wasted time.

First of all, you need to check:

• Are the speakers connected to the PC and the jack used matches the destination device.
• The location of the plug if the speakers are powered from an electrical outlet.
• In what position is the volume control. Perhaps it is twisted "to zero".
• Is one of the connecting cords damaged?

Often just such "platitudes" push a person to wrong actions. Therefore, be careful. Connect speakers that are known to be working. Perhaps all your fears are in vain!

Step # 2. Discover the "secret" signs

In the event that the sound on the computer has disappeared, pay attention to the speaker-shaped icon located in the system tray. It may be crossed out to indicate deactivation of the playback device. Move the slider up. If everything remains unchanged, proceed to the next solution point.

Step # 3. Windows services

It's no secret that the operating system has incredibly wide functionality. Management and control in the OS is carried out by special services, one of which is responsible for the playback of audio material. It is simply impossible to fully customize sound on a computer without Windows Audio. Therefore, you need to check the current status of this service.

• Use the Win + R hotkey combination to bring up the Run menu.
• In the window that opens, enter the services.msc command. After confirmation with the "OK" button, you will be redirected to a special section "Services".
• Find Windows Audio in the list provided.

For sound to play and audio settings to be correctly recognized by the system, make sure the service is active. That is, the "Status" column contains the "Running" parameter, and the "Startup type" column is set to "Automatic". You can make the necessary changes using the same right mouse button, placing the cursor on the item that requires the corresponding revision.

Step # 4. The driver that can crash

A crossed-out speaker in the tray may also indicate the inability of the special program code that controls the audio chip. In other words, the sound on the computer disappears when the driver becomes inoperable.

• Open the start menu.
• Then go to the "System" section.
• Select "Device Manager" on the left side of the window.

It will not be difficult for you to find the "culprit" of a problematic situation. In the presented list, a non-working device will be marked with an exclamation or prohibitory mark. Update the sound driver using the service disc (software for the motherboard from the kit). In the absence of such, you need to go to the official website of the manufacturer and in the "Support" section download the appropriate modification of your PC software tool. It should be noted that before installing the latest version of the sound driver, you must remove the old device control component.

Standard Windows functionality

When all your attempts at practical actions to answer the question of how to turn on the sound on the computer have not brought fruitful results, it makes sense to use the incredibly convenient option "Troubleshooting". However, this functionality is only available in later versions of the Windows operating system. To run this tool for correcting conflict situations, you need to right-click on the conflicting device (indicated by the system with a special warning sign) and select "Diagnostics and correction" in the context menu. After a few minutes, the OS will notify you of the result of the work performed. It is likely that such a sound setting on a computer will be an effective salvation for a seemingly "dull" situation.

Step # 5. Settings

If you are convinced that the driver is installed correctly, and the service window of the sound device "Properties" displays the current state "Works normally", then the solution to the question "how to turn on sound on the computer" should be sought by the following algorithm of actions:

• From the Start menu select Control Panel.
• Go to the "Sound" section.
• In the window that opens, right-click on the icon of the displayed playback device. Select "Properties" from the context menu.
• While on the "General" tab, pay attention to the "Device Application" item below. More precisely, the value in the checkbox. Apply the On option.

In the case when there are several installed playback devices in the mentioned list, one of them should be assigned the "Default" value.

Step # 6. Audio controller

As a rule, in most of the manufactured motherboards the extended sound scheme is implemented. That is, the integrated audio chip can be controlled by a specially installed driver. Let's take a look at an example where the sound setting on a computer is done through the Realtek HD Manager.

• Click on the speaker icon (darker in color and slightly larger than the standard Windows volume control).
• In the dispatcher's working window that opens, activate the icon in the form of a wrench (lower part of the interface, on the right).
• In the case when the sound is not reproduced, it is necessary to change the scheme from one value to another (meaning "Front panel of the AC" 97 "and the item of the same name located just below).

Often it is this change that allows you to use the required audio channel.

Step # 7. Incomprehensible multimedia format

There are frequent cases when audio playback on a computer is impossible due to a missing audio codec. This difficulty can be easily corrected.

• Enter K-Lite Codec Pack in the search bar of your browser.
• Then select the official source of the product from the list provided.
• Download and install the required software.

Typically, this action gives the PC an "omnivorous" multimedia ability. Rest assured that your computer will not be an exception to the rule.

Step number 8. Software incidents

It so happens that after installing a certain software, the sound disappears, and after uninstalling the conflicting program, it reappears. Some media players play a limited number of audio and video formats. This is the only reason why often unlucky users start to panic. Therefore, before installing any program for viewing and playing multimedia content, you should refer to reviews of the product and a review of its tactical and technical capabilities.

Step number 9. Look for the reason in the BIOS

As you know, the BIOS firmware controls and monitors the operation of the entire hardware of a computing device. So installing sound on a computer may turn out to be an impossible mission when the audio functionality is disabled in BIOS for some unknown reason. However, knowing the main rule when working with the basic system: "Do not touch or change unknown values", you will successfully cope with the task.

To check if the audio function is enabled in BIOS, you need to do the following:

• Log into your PC's Bios.
• Depending on the BSVV version, the location of the sound "switch" may differ. However, the name "AUDIO" and the value "Enabled / Disabled" or "On" are unchanged.
• Finding a tab with the Onboard Device Configuration option, or High Definition Audio, is not difficult. The main thing is to understand the seriousness of the enterprise and not make rash changes to the firmware. Since it is fraught ...

Step # 10. System Restore

If, after all the manipulations, the question of how to install sound on the computer remains unresolved, then it would be prudent to use the method presented below.

• Go to the start menu.
• Enter "restore" in the search box.
• After the search section is displayed at the top of the service window, press Enter.
• Select the required backup and confirm your choice with the corresponding button.

After rebooting, the system will regain the ability to play sound.

Step 11. Damaged or missing OS files

Sometimes the question of how to make sound on a computer is solved by restoring the lost entries in the system registry. Indeed, very often the user, as a result of erroneous actions (usually in the pursuit of free space on the hard disk), deletes important OS data. Ultimately, the inevitable happens - Windows loses full functionality. However, the unfortunate user does not always have the opportunity to roll back the system to its original state. By the way, the same well-known reason is to blame for everything - saving space on the HDD, that is, there are simply no backups of the OS, since System Restore is deliberately disabled. Nevertheless, even in such a situation, there is a way out.

• Press the Win and R keys at the same time.
• In the Run menu, type cmd.exe
• · In the command window, write sfc / scannow.
• Hit Enter.

The damaged data will be restored from the backup storage. It is likely that after restarting the OS, you will hear the sound greeting again.

Step number 12. Viral infection

Malicious code not only steals and destroys user data. A virus program that has infiltrated the operating system environment can also be the reason for the loss of sound on the computer. In order to identify the pest, special software is required. The anti-virus program traditionally used for protection is not quite enough. However, today there are plenty of effective malicious code destroyers on the Internet. Therefore, you should not have much difficulty in the process of finding the necessary software tool.

• To ensure that your PC never has sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) to see if more recent drivers have been released.
• Connecting devices for audio playback to the system connectors of the PC, it will not be superfluous to understand in more detail the correctness of the connection scheme involved.
• Often motherboards have special contact pads that can be closed with special jumpers in order to remap the audio output. Therefore, it is worth referring to the documentation of the motherboard and study the problematic issue in more detail.
• If all methods are in vain in terms of your expectations (which is unlikely to happen), seek specialized help.

How do I connect audio on my computer? As you can imagine, this is an incredibly large-scale question. However, today you have learned a lot of information about what needs to be done in order to "talk" your electronic friend, and what you should be wary of while using it. All the best and pleasant sound impressions to you!

The release of new operating systems also brings unpleasant innovations: some do not like the new design and the lack of familiar buttons, some find it difficult to interact with the system and configure it. Let's get started with Windows 7. How to customize sound and make it high-quality - you will learn about this in this article.

Sound setting in Windows 7 is carried out through the control panel and allows you to configure the microphone, speakers, sound effects. The sound setting method is different from the setting in Windows XP. Some changes have been added to the control panel that may seem unusual for users of other operating systems. But, in fact, there is nothing complicated in setting up sound in Windows 7.

Let's go to the control panel. In order to access the sound settings, you need to select the section "Hardware and Sound" -> "Sound" - it is quite logical, in general. We will open a settings window, the interaction with which we will study.

The audio settings window is divided into several tabs: playback, recording, sounds and communication. Let's get acquainted with them in more detail.

Sound Playback Settings

The "Playback" tab shows us a list of devices that can play sound. Devices currently in use are marked with a green checkmark, and disabled devices are marked with a red down arrow. Here devices are not only physically connected to the computer, but also those that can be connected in principle - i.e. sound adapters for which drivers are installed. Select the active device and click the "Configure" button. Here we can configure the playback device.

First, we set up the speakers based on the number of audio channels. If you are using headphones or regular speakers, then our choice is “Stereo”. If you have a more advanced audio system connected, then you can choose "Quadraphonic" or "5.1 surround sound" or it, but in the "7.1" option. By clicking the "Next" button, we can indicate the location of the speakers, which of them are broadband and other useful things.

If on the "Playback" tab, click the "Properties" button, then we will see a window with additional settings for the audio device. Here we can turn the device on or off; change its icon and specify the sound format, adjust the effects of sound playback.

Sound recording

Let's go back to the general settings window of Windows 7. How do I configure the recording sound? This is also not difficult. The Recording tab provides similar settings, but now for recording devices. If you select a microphone and click the "Configure" button, a speech recognition window will open. Unfortunately, Windows will inform us that speech recognition is not supported for the Russian language. The "Properties" button may be of more use to us, clicking on it opens a tabbed window. setting up sound in Windows 7 isn't the hardest thing to do, is it? On the General tab in the microphone properties, brief information about the device is displayed. The "Listen" tab allows you to connect a player or other devices to listen to music; on the "Levels" tab we can change the volume and gain of the microphone, and on the "Levels" page there are settings for the bit depth and bit rate. The Improvements tab gives us the ability to enable various sound effects.

The other general sound settings tabs in Windows 7 are helpful too. On the "Sounds" tab we can change the used sound scheme, and the "Communication" tab allows you to decrease the volume of sounds during conversations - convenient and understandable! We hope this article helped you familiarize yourself with Windows 7. How do I set up sound? It's easy, because now you yourself can share your experience!

Surely you have experienced situations when after a reboot the sound on the computer suddenly disappeared. This problem deprives you of the opportunity to fully use the device: you can neither listen to your favorite songs, nor watch videos, nor play online games.

In short, your laptop or personal computer has actually become a typewriter. To restore the system to work, all you need to do is change some settings.
Considering all the existing variety of electronic devices and operating systems, you can give some more or less general advice on sound tuning.

Sound settings for Windows 7

Suppose that you are not working at a laptop, but at a stationary computer, to which many additional devices are connected, such as a keyboard, mouse and, of course, a speaker system. But suddenly the sound disappeared. You have checked all the connections and settings of the installed drivers. Everything seems to be in order, but there is still no sound. How do you fix this problem?

There can be many reasons for such a problem: from simple bending of the wire, and the inoperability of the sound card, to the incorrect installation of the drivers. Without identifying the root cause of the problem, you will not be able to recover the sound. It is necessary to understand how sound is configured in Windows 7.

Possible reasons

Any device has its own unique structure and technical characteristics. Using each of them as an example, we will analyze the most probable reasons for the disappearance of sound.

The first device we'll look at is a laptop. First of all, you need to check the speaker volume settings. The sound was probably muted by pressing a key combination on the keyboard.

If there is no sound on a stationary computer, the first step is to check if the drivers are installed correctly. If everything is ok with the drivers, you can try restarting the operating system. Also, a possible cause of the disappearance of sound may be a malfunction of the sound card. In this case, the problem is unlikely to be resolved quickly. Most likely, the computer will have to be handed over for repair, or buy a new sound card.

In order not to check all sorts of options for the reasons for the disappearance of sound, on any OS there are special programs, the purpose of which is to fix any problems.

Checking the performance of the sound card

To check the sound card of your computer, you need to go to the "Start" menu item "Control Panel". Next, find the "System and Security" section and select Device Manager. The window that opens allows you to diagnose all devices connected to the PC. You can check the sound card in the same way. If you find it in the list of audio and video devices, then it is installed correctly. If there is no sound card in the list of devices, you need to activate it. In laptops, this system is organized a little differently. It has an integrated sound processor, so you may not find the item you want in the Device Manager list.

If you encounter problems with the sound card, you will see a yellow question mark next to the device label. It is necessary to click on the selected device with the right mouse button, select "Properties" and analyze the problem. In some cases, simply installing a new driver is sufficient. Thus, you can quickly solve the problem of the disappearance of sound.

Checking device connections

Before looking for suitable drivers for your sound card and installing them on your PC, try to check if all speaker cables are connected correctly. If you are using stereo headphones with a microphone, check if they are connected correctly. It may be enough to simply plug the audio cable into the desired connector. PC manufacturers usually mark their audio inputs and outputs with different colors. The pink output is for a microphone, and the green is for headphones or speakers. Also near the inputs there is an icon depicting a microphone or headphones.

If you are going to use an HDMI cable on your PC, then be prepared for the fact that not all video cards support sound in this format. There is a default HDMI audio device you have to install. To check the ability to support sound by a video card, you need to go to the "Start" menu, select "Control Panel" and the "Sound" tab. Next, you need to select the HDMI device, click on the "Set as default" and confirm the selected action.

If you are using USB devices and you have lost sound on your computer, then you can try restarting your PC, pull out and insert the plug of the audio device into the USB port. In some cases, you just need to wait a while for the PC to automatically configure the USB driver.

Cartoon devices

Most personal computers today have multiple audio inputs. Some of them may be located on the front of the system unit, and some on the back. Perhaps one of the connectors you are using is simply defective. Then it is necessary to check the functionality of both inputs. There is also the possibility of damage to the connecting cable. It is quite easy to detect this problem, you just need to connect headphones or other audio device to your computer and check if it works.

Checking the audio output volume
